Study Notes
Microprocessor Architecture
- Objectives of the lecture include understanding the internal configuration of the microprocessor, addressing modes, and program-visible registers.
- The lecture is based on chapters 2 from "THE INTEL MICROPROCESSORS" by Brey (8th Edition, 2009) and chapters 1, 8, and 21 from "80X86 IBM PC and Compatible Computers" by Mazidi (4th Edition).
Addressing Modes
- Addressing modes for the 8086-Core2 microprocessors are described for real, protected, and flat modes of operation.
Program-Visible Registers
- The function and purpose of each program-visible register in the 8086-Core2 microprocessors, including 64-bit extensions, will be discussed.
Flag Register
- The flag register and the purpose of each flag bit will be examined.
Memory Access
Real Mode
- Real mode memory-addressing techniques will be described, including how memory is accessed.
Protected Mode
- Protected mode memory-addressing techniques will be described, including how memory is accessed.
64-bit Flat Memory Model
- The 64-bit flat memory model will be described, including how memory is accessed using this model.
Program-Invisible Registers
- Program-invisible registers found in the 80286 through Core2 microprocessors will be described.
